Step-by-Step Winterization Process
Alright, let’s talk about winterizing your RV!
First things first, you’ll want to start by fully draining your black and gray tanks. It’s a crucial step to make sure everything is nice and clean. Remember that water weight can add significant load, so draining helps reduce unnecessary strain on your RV during winter.
Once that’s done, don’t forget to bypass the water heater. This is super important because we want to prevent any antifreeze from getting into it. Many RVs include additional systems like ice makers and dishwashers that need special attention.
Now, onto the fun part! You’ll need to circulate some RV-approved pink antifreeze through all the water lines. You can use a converter kit for this. Just keep an eye out for that antifreeze – you want to see it coming out of every faucet and toilet.
Oh, and here’s a little tip: make sure to pour some antifreeze down each drain and into the toilets. This will help protect the P-traps and prevent any freezing in those traps and outlets. Using tanks made from BPA-free polyethylene can also contribute to maintaining water quality during winterization.
Drain and Bypass
Draining and bypassing your camper’s water system guarantees that no water remains to freeze and cause damage during winter storage. Start by fully draining the freshwater tank through its designated valve or plug. Open all faucets to allow air in and speed drainage.
Don’t forget to remove the water heater’s drain plug and open its pressure relief valve to avoid trapped pressure.
Next, open all low-point drain valves under the camper and operate fixtures separately. Purge residual water from supply lines and traps until flow stops or antifreeze appears.
Install or operate the water heater bypass valve to prevent antifreeze from entering the heater. Confirm bypass functionality by running the water pump briefly.
Only close low-point valves after confirming complete drainage or after antifreeze steps. Using durable RV hoses during winterization can help prevent damage from freezing and ensure reliable waste management.
Antifreeze Circulation Steps
After draining and bypassing your camper’s water system, the next step is to circulate RV-safe antifreeze through all water lines and fixtures. Using a non-toxic antifreeze ensures safety for drinking water systems during winterization.
Use only non-toxic, propylene-glycol antifreeze rated for potable water. Connect a siphon or adapter to your water pump inlet and submerge it in a container of antifreeze.
Activate the pump, then open faucets one at a time, starting closest to the pump, until pink antifreeze flows steadily from both cold and hot sides. This process prevents residual water from freezing and causing damage.
Run antifreeze through all outlets, including kitchen, bathroom, exterior showers, and appliances. Don’t forget to flush toilets until antifreeze appears in the bowl.
If your pump bypass isn’t available, pour at least 4 gallons into the freshwater tank and cycle the system similarly. It’s also important to sanitize your fresh water tank regularly to avoid contamination during storage.
Finally, pour antifreeze into all drains and traps to protect seals and prevent freeze damage.
Managing Interior Heat to Prevent Freezing
To keep your camper pipes from freezing, it’s a good idea to run the furnace continuously. This helps circulate warm air and keeps the pipe temperatures up. You might also want to keep your water heater powered on and set it between 140-160°F. This way, the connected lines stay nice and warm.
Now, maintaining a consistent warmth inside your camper is key. When you combine that with proper insulation, you’ve got a solid defense against freezing conditions. Additionally, insulating fresh water tanks can help retain heat and prevent freezing during cold weather.
So, remember to check those settings and keep things cozy! Using quality seal conditioners on rubber seals can also help maintain their flexibility and prevent damage caused by cold temperatures.
